EVERYTHING YOU NEED TO KNOW TO SELL THE
SL 1000-B1 SLIDE GATE OPERATOR
The Basics
FRAME
1/4 inch cold rolled steel that has been gold zinc plated for resistance to moisture and
other corrosive elements.
MOTOR
Leeson 1/2 horsepower, single capacitor, 115 VAC.
GEARBOX
30:1 wormgear reduction in synthetic lubricant that won’t thicken in cold temperatures.
LIMIT SWITCH
ARRANGEMENT
Gearbox has integral, threaded shaft opposite from drive shaft. Two nuts, made
from self-lubricating plastic, move along shaft as gate is moved, contacting switches
located near the ends of the shaft. Adjustments are precise to within 1/2 inch. Allows
gate to travel more than 40 feet.
CHAIN
Size 40 provided as standard for long service life.
GATE SIZE LIMITATIONS
Operator can handle gates up to 40 feet long and weighing as much as 1000 pounds.
INTEGRAL
ACCESSORY TRAY
Made of 14 awg gold zinc plated steel, this tray provides space for loop detectors,
other accessories and LiftMaster’s Power Fail Operation option.
COVER
Spin molded ABS plastic in medium gray color with decorative ribbing parallel to
direction of gate travel.
DIMENSIONS
15.25 inches wide by 20 inches deep by 25.75 inches high.
OPERATOR POWER
115 VAC, 60 Hz using dedicated 15 amp or 20 amp circuit. On/Off switch provides
easy power disconnect during installation and servicing.
ACCESSORY POWER
24 VAC power is provided for a radio receiver, as well as two 115 VAC utility plugs.
CONTROL INPUTS
Operator has separate inputs for Manual Open, Close and Stop (used for three button
station), Cycle (used for devices such as telephone entry, etc.), Fire, Radio Receiver,
Exit Loop, Inside/Outside Interrupt Loops, and Interrupt Bar. Cycle and Radio
inputs can operate in push to open/push to close manner. Each input is protected
against voltage spikes by surge suppressers and opto-isolators.
RIGHT/LEFT OPERATION
Switch on board lets installer specify whether gate opens right or left.
TIMER
Adjustable from 1 - 250 seconds.
MAG LOCK CONTROL
Relay provided to activate and deactivate magnetic lock on gate.
115 VAC SWITCH
AND RECEPTACLES
A switch box and on/off switch is pre-installed for easy connection of 115 VAC power
to the operator. Two utility plugs are provided for 115 VAC accessories and/or installer
tools. Connections to switch, utility plugs, and operator are all pre-wired for your
convenience.
WARRANTY
3 years on mechanical assemblies and 2 years on electronics.
POWER FAIL OPERATION
This option can be ordered pre-installed or in kit form. Includes DC motor, 12 volt
gel cell battery, larger V belt, and motor control relays (mounted on a bracket which
secures battery to accessory tray). All battery charging circuitry already contained on
SL 1000-B1 control board. No auxiliary limit switches to install. May be set to drive
gate to open limit or to close limit when AC power fails. Built-in momentary delay
ensures that brown-outs do not cause “false starts”. A crank is provided for manual
opening of the gate if the Power Fail Operation option is not purchased.

Other Important Features
DIAGNOSTIC LEDs
There is a status LED for every input and output. Combined with the separate inputs for
every type of device, these LEDs make installation and troubleshooting a snap.
DYNAMIC BRAKING
Provides quick, precise stopping of the gate and eliminates gate coasting.
PLUG-IN
LOOP DETECTORS
The gate operator comes with three convenient built-in connectors which accept
LiftMaster-supplied plug-in loop detectors. Instead of wiring through relay inputs, now
inside/outside interrupt loops and exit loops can be plugged directly into the gate
operator board, greatly simplifying installation of the complete system.
TAILGATING
SUPPRESSION
When car enters and then clears the inside interrupt loop while the gate is being
opened, the operator stops the gate and then starts to close it. If a second car comes
onto the inside interrupt loop, operator stops the gate but does not reverse direction.
When the loop clears (presumably by second car backing off loop), the operator
finishes its closing operation. This feature may be turned off if not needed.
IMPROVED SAFETY
CAPABILITIES
If the gate hits an obstruction when opening or closing, the operator stops and then
backs up. The operator can be set either to suspend operation immediately if it hits
something, or to try continuing its operation twice before suspending operation.
Operator has separate obstruction sensitivity adjustments for opening and closing,
allowing the installer to adjust the gate on unlevel surfaces (e.g., less sensitive
going uphill than downhill, since uphill travel appears as resistance to the operator).
MASTER/SLAVE
CAPABILITY
OPTIONS
Page 2 of 3
LiftMaster Master/Slave systems provide synchronization, added safety, reduced wiring
and simplified gate control settings. Two SL 1000-X1 Slide Gate Operators can be
teamed in any of four different configurations: Bi-Parting, Bi-Parting Latch, Trap and
Tandem.
Power Fail Operation Option: See bottom of previous page.
Loop Detector Modules: Plug directly into the control board, reducing cumbersome
wiring and valuable installation time.
